A bit of time with the 1.4x converter

Have had it for a while now and my main thoughts are with the 300DA* and 100mm DFA WR Macro:-
1.No change in focusing characteristics - you don't know it's there
2. No noticable change in sharpness
3. Possibly a slight drop in resolution, eg in feather detail but not sure about this yet as I haven't fine calibrated the combo yet
4. Very handy for butterflies and dragonflies - gives you same size image from slightly further away. In some instances not much different to cropping but at the limit of desirable cropping slight advantage.
This Kingfisher pic is with the DA*300 and is about a 65% crop.

It's a great TC Dave, no doubt about it. Mine is almost permanently attached to the DA*300 when I take this lens out. I also like the fact that it's small enough to whip off and stick in your pocket when not required. It really is a gem of an accessory.

Regards
David

PS: Fabulous shot of the Kingfisher, wish I knew where to go to get images like this!

All I need now is to find a bloody kingfisher

A lovely image, that converter works a treat

Agreed about the kingfisher image, and nicely placed in the frame too.
Anyone used the 1.4TC with the Tamron 70-200 f2.8??

Not tried it but have both so can try for you

Thank you, very kind.

I have used a cheap Tak-A 2x converter (Which I got to turn into an auto extension tube) with the Tamron with not awful results, so I am interested in how this combo works, IQ probably more of interest than AF as I have been using MF for the above combo.

Can say aok IQ seems same dragonflies watch out

That is encouraging!

It might tempt me to get a DA*300 too in the fullness of time....
